Reproduce code: --------------- http://www.hshh.org/temp/test.phps Script is UTF-8 Simplified Chinese string pcre_replace testing. I was also tested replace PCRE lib of php 5.2.0 from 6.7 to 6.6 not bundled, no different result. Expected result: ---------------- FreeBSD, PHP 5.2.1, process time: 3.76s (dual p3-1.26G). Windows2003, PHP 5.2.0, process time: 17.91s (Pentium-M 1.7G) If I don't set 'pcre.backtrack_limit' to '-1', script will break pcre_replace.
